1. Checking the rotating state of a rotor assembly Check
tis rotating state when strange noise is heard during
rotation. If you use a sound rod, contact the neb of
the sound rod to the turbocharger housing and slowly
raise the RPM. If high-pitched sound continues, it
means that the state is abnormal. In this case, the
bearing or the rotor assembly may be abnormal. So
you need to replace or repair the turbocharger.
2. Checking the play of rotor assembly Remove a turbo-
charger from the engine, and check the axial and
radial play of the rotor assembly. When you disas-
semble the turbocharger, be sure to seal the oil inlet
and outlet with a tape, etc.
